To @Z3 whom it may concern:

Be it known that I, CHARLES C. Hoorn, a

citizen of the TJnited States, residing at vCleveland, in the county ofCuyahoga and devices upon sharp and reverse curves; the

provision of a coupler having improved means for securing its verticaladjustment; the provision of a coupler having a pin and rollers as in myprior patented structure above referred to in which the opposing lipsengaging the rollers are spaced apart a sutlicient distance to permit asubstantial vertical movement of the coupler link, and in which therollers are maintained in full engagement with the said lips; theprovision of a coupler of the character specified having improved meansfor securing the-assemblage of the pin and rollers in the couplerpocket; and the provision of a coupler of the character specifiedwherein the lateral movement of the link and rollers may be limited andadjusted as desired. Certain embodiments of the invention areillustrated in the' accompanying drawings, wherein- Figure 1 is a planview of the coupling.

apparatus, with the parts in one position of use; Fig. 2 is a frontelevation of the cou-V pler head upon the bumper beam, with the rollersand link removed; Fig. 3 is a section ou the line III-III of Fig. 1, butwith the rollers and link shown 'in position inv the head; Fig. l is asection'on the line Ill-IV.

of Fig. 1; Fig. is an end view of the securing pin shown in Fig. 3, Fig.6 is a side elevation of the rollers and pin as employed in thepreferred type of construction.; Figs.

7, S, and 9, are sections through modified forms of pin and rollerconstructions, and Fig. 10 is a plan view of a modi tied form of couplerhead construction.

In Fig. 1 two forms `of coupler head are illustrated, both of which,however, embody the same general principles of construction, the head Abeing of the type employed upon the bumper beam of switching locomotive,and the head B having a shank correspondjing up i.

ing to that of the ordinary coupler and being applicable to thelordina-ry type of car. The two heads as illustrated in Fig. 1 show theposition of the parts when the two cars are upon a curve which causesthe heads to shift laterally with respect to each other.

-As indicated in Fig. 3 the head A is provided with a pair ofoverhanging lips 1 and 2, between which is the slot 3 for the usualcoupling link 1. Mounted in the head is the pin 5 carrying the rollers 6and 7 such rollers engaging respectively the overhanging lips 2 and 1.As indicated in Figs. 3 and 6 the lower roller 6 is provided with aperforation 8 extending clear through the roller, while the upper roller7 is provided with a perforation 9 which passes only part way throughthe roller, so that when the roller 7 is'placed upon the pin 5 it cannotdrop below the position indicated in Fig. 3.

The feature of supporting the upper roller 7 so that it cannot drop downbelow the position indicated in Fig. 3 is advan tageous, as vthispermits the slot 3 to be made as wide as may be desired, and at the sameytime insures that the entire bearing face of the roll 7 will alwaysengage the overhang- 'This would not be the case if the roller 7 were soconstructed that it could slide down until it engaged the coupler linkas in my prior patented construction. It will be seen that it isimportant to have a relative wide slot 3 in order to permit of thevertical adjustment of the link 4t, as the coupler head with which thehead A may be used may lie at aheight considerably above or below theposition of the head A, thus .necessitating the tilting of the linkeither upward or downward.

In order to permit of the assemblage of the pin 5 and rollersG and 7, aperforation `10. is yprovided through the bottom wall of the pocket A(Fig. 1). -The head B has a corresponding perforation in its bottom wall(Fig. 4f), and in this head as in the head A (Fig. 2) the perforation isclosed by a cap 11 which serves tol prevent the pin from coming outaccidentally after the parts have been assembled. This cap 11 isinserted from the interior of the head, Vand is held against accidentaldisplacementby means of a Cotter 12. The closure means 11 is the samefor the two heads A and B, the only difference being as to location, asindicated in Fig. 1, and the construction will be readily understood byreference to Fig. Ll in conn nection with Fig. l. ln assembling theparts the two rolle-rs 6 and 7 are placed over the perforations in thebottom wall of the head, and the pin inserted from beneath, the link atsuch time of course lying between the two rollers. The parts are thenmoved from their position over the perforation and the cap ll isinserted to prevent the accidental displacement of the pin subsequently.

ln Figs. 7, 8, and 9, alternative arrangements are shown formaintaining` the upper roller in its eXtreme upper position. In theconstruction of Fig. 7 the pin 5 carries the rollers l and 7, the upperend of the pin being' reduced as indicated at 13, in order to provide ashoulder to prevent downward movement of the roller 7. This arrangementis less advantageous than the ar 1ange ment shown in Fig. 6, as therollers G and 7 are not interchangeable. ln the construction of Fig. 8the pin 52 carries the rollers G2 and 72, the upper roller being heldagainst downward movement by means of the sleeve '14. In theconstruction of Fig. 9 the pin 5:" carries the rollers G3 and 7 "i, therollers being cast upon the piu so that the roller 7 i' cannot approachthe roller G3. ld hen the construction of Fig. 9 is employed the partscannot oit' course be assembled as heretofore described, and it isnecessary to provide au opening into the interior of the head largeenough to insert the three parts in their assembled position. This isdone as indicated in Fig. 2, by providing the opening lo through therear wall of the head, so that these parts are necessarily assembledbefore the head is applied to the bumper beam. lrlhen this constructionis used the coupler link must either be applied to the pin 53 before therollers are cast thereon, or else the link. must be distorted iu orderto permitthe passage of one of the rollers and subsequently pressed backinto its proper place.

The bca-d A is preferably held in place upon the bumper beam 16 by meansof the clamping members 17 and 18 (Figs. l and 2), such clamping membersbeing secured in position by means of the bolts 1Q. ln order to make thesupport of the head more positive the beam 16 is preferably providedwith the strap Q0 Figs. l, 2, and 8), which strap is provided with a,series of perforations 21. The coupler head is provided with lugs 22 and23 upon its upper and lower sides, which lugs have transverseperforations adapted to aline with one of the periterations Q1,depending upon the height to which the head is adjusted. A locking pinQ-l passes through the alined perforations and is held in place by acot-ter 25. A considerable range of adjustment is thus secured, and themaking of the head symmetrical upon its upper and lower sides permits-ofthe use of the head with either side down. The locking pin 24; isflattened upon one side as indicated at 26 in Fig. 5, so that it willlit close against the wall of the head, the eotter 25 passing throughthe wall of the header, preventing any outward movement. The upper wallof the header .A is also provided with a perforation 27 (Fig. l) for thereception of a cap corresponding to the cap 1l, when the head isinverted.

The upper and lower walls of the head A are provided with a series ofperi'orations 28. W'hen desired, the lateral movement of the rollers inthe head may be .limited by placing pins through these holes, such pinsextending through the alined holes in the upper and lower walls of thehead. The holes also serve to drain the pockets between the stiffeningribs 2S). ln Fig. 2 a pin 8O is shown as extending through two opposingholes 28, for limiting the movement of the rollers to the right.

The head B as shown in section in F -l corresponds throughout to thehead A, eX- ccpt as to length, and with the further difference that thishead provided with the usual coupler shank. Fin 54 and rollers G4' and7AVL correspond throughout to the parts (l, and 7 of the structure ofFig. 8, with the exception that the rollers are somewhat smaller. Theparts are assembled through a perforation in the bottom wall of the headas heretofore described, such perforation being closed by means of thecap l1, after the parts have been assembled. The top and bottom walls ofthe head B are provided with the perforations 8l, corresponding infunction to the perforations 28 in the head A.

Fig. l0 illustrates a modified type of construction wherein the head 82and bumper beam are made in one integral casting secured directly to theengine frame members S4-34. rlhe rollers and pin used with thisconstruction are precisely the same as in the construction of Figs. l,Q, and 3, and the walls are provided with the perforations correspondingin function with that of the perforations 28 in the construction of Fig.l. rilhe pin 86 is shown in position in one set of the holes 35, forlimiting the lateral movement of the rollers in the head. The centralportion of the head is provided with a pair of alined perforations 87 inthe upper and lower walls, to permit of 'the insertion of an ordinarycoupling pin when it is desired to use an ordinary coupling bar orcoupling link in the usual manner. Similar perforations 88 and 39 areprovided in the heads A and B.

Having thus described my invention and illustrated its use, what I claimas new and desire to secure by Letters Patent, is the following:

l. In combination, a hollow transversely extending head slotted alongits front side and provided lwith opposing overhanging lips spaced apartto permity vertical play of the hereinafter mentioned coupling link, avertical pin in the head, a bearing roller on the upper end of the pinwit-h its bearing edge in engagement with the upper lipv and heldagainst downward movement on the pin, whereby the said roller ismaintained against decreasing its bearing engagement with the upper ofthe said overhanging lips, a roller mounted on the lower end of the pinwith its bearing edge in engagement with the lower lip, and a couplinglink on the pin intermediate the rollers, the said rollers being spacedapart so as to permit a vertical movement of the link along the pin.

2. In combination, a hollow transversely extending head slotted alongits front side and provided with opposing overhanging lips and havingits lower wall perforated to permit the passage of a bearing pin, abearing pin, a lower roller perforated to permit the passage of the pin,an upper roller adapted to receive the upper end of the pin,interengaging parts on the pin and upper roller for preventing the upperroller from moving downward from its position at the end of the pin, anda coupling link lying between the overhanging lips and embracing the pinbetween the rollers.

3. In combination, a hollow transversely extending head slotted alongits front side and provided with opposing overhanging lips and havingits lower wall perforated to permit the passage of a bearing pin, abearing pin, a lower roller perforated to permit the passage of the pin,an upper roller adapted to receive the upper end of the pin,interengaging parts on the pin and upper roller for preventing the upperroller from moving downward from its position at the end of the pin, aVcoupling link embracing the pin between the two rollers, and means forclosing the perforation in the lower 'wall of the head after the pinrollers and links have been assembled.

4. In combination, a hollow transversely extending head slotted alongits front side and provided with opposing overhanging lips, a verticalpin in the head, bearing rollers on the ends of the said pin andengaging the said overhanging lips, and a link on the said pin, theupper and lower walls of the head being perforated on either side of thecenter line of the head to .permit the insertion of pins to limit thelateral movement of the rollers and link.

In testimony whereof I have hereunto signed my name in the presence ofthe two subscribed witnesses.
